In modern day Mold Production, with the degree of the plastic parts of the stunning and functional needs larger and larger and plastic parts are made to be more complicated internal structure, the mold shape style are becoming increasingly complicated and ever-escalating proportion of free of charge-kind surface, the corresponding mold structure is also made to be a lot more complex. All of the mold process place a larger demand, not only to guarantee the manufacture of high precision and surface top quality, but also to the pursuit of processing of the surface appearance. With higher-speed machining technology continued to deepen, especially in the processing Machine tool , CNC systems, tool systems, CAD / CAM software program and connected technologies continues to develop, driven by higher-speed machining technology has been increasingly applied to the mold cavity of the processing and manufacturing.

CNC higher speed machining in mold generating, as 1 of the most critical sophisticated manufacturing technologies, is a extremely efficient, higher quality, low energy in an advanced manufacturing technology. Compared with the conventional cutting, the cutting speed, feed price has been significantly improved, and the cutting mechanism is not the very same. High-speed cutting to cutting essential leap took place, the unit energy of the metal removal rate increased by 30% to 40%, 30% reduced cutting forces, cutting tool life increased by 70%, to remain in big components of the cutting heat decrease rate, low cutting vibration virtually disappeared. With the boost in cutting speed, rough material removal rate per unit time increases, the cutting time is decreased, and processing efficiency, and thereby decreased the manufacturing cycle and increase the market place competitiveness of merchandise. At the identical time, high-speed processing of little quick-forward to lessen cutting force, chip, higher-speed discharge to reduce the workpiece deformation of the cutting force and thermal stress, boost poor rigidity and the possibility of cutting thin-walled parts. As the cutting force reduction, increase speed to make the program work cutting away from the machine’s low frequency organic frequency, while the workpiece surface roughness on the most sensitive to low frequencies, thereby lowering the surface roughness. In the high-hardened steel mold (HRC45 ~ HRC65) machining method can be replaced by higher-speed cutting and grinding EDM polishing processes, as a result avoiding time-consuming electrode manufacturing and processing power, drastically minimize the fitter’s amount of grinding and polishing. For some markets a expanding need for thin-walled mold parts, high-speed milling can be successfully completed, and in high-speed CNC machining center, milling, die in a single setup to complete multi-step approach.

High speed machining of mold processing technology had a tremendous impact, changing the standard mold used “annealing heat treatment milling grinding” or ” EDM grinding, polishing,” and other complicated and lengthy method even be utilised option to the original high-speed machining of all processes. Higher-speed machining techniques can be applied to the direct processing of hardened mold cavity (specifically semi-finishing and finishing), the electrode in EDM machining, manufacturing, speedy sample also extensively used. Mass production practice shows that the application of high-speed die cutting technologies can save about 80% of comply with-up processing of manual grinding time, saving processing costs nearly 30% of the expense of the mold surface machining accuracy up to 1m, tool cutting efficiency can be increased by 1.
